Abstract
Methods, apparatuses and systems are provided for grant-less (GL) uplink transmissions. A wireless transmit/receive unit (WTRU) may receive a configuration of a set of GL Physical Uplink Shared Channel (GL-PUSCH) frequency resources. The WTRU may monitor for a downlink control information (DCI) message, wherein the DCI message includes an indication of a presence of at least a subset of the set of GL-PUSCH frequency resources. If the WTRU successfully receives the DCI message, the WTRU may select one or more GL-PUSCH frequency resources from the subset of the set of GL-PUSCH frequency resources and may select a time period. The WTRU may transmit data on a GL-PUSCH using the selected GL-PUSCH frequency resources during the selected time period. The WTRU may also monitor for hybrid automatic repeat request acknowledgement (HARQ-ACK) based on the selected GL-PUSCH frequency resources. The WTRU may monitor for the DCI during a fixed time window.

Claim
1. A method for use in a wireless transmit/receive unit (WTRU) for multiple access wireless communications, the method comprising:
receiving, by the WTRU, a configuration of a set of grant-less Physical Uplink Shared Channel (GL-PUSCH) frequency resources; monitoring, by the WTRU, for a downlink control information (DCI) message, wherein the DCI message includes an indication of a presence of at least a subset of the set of GL-PUSCH frequency resources; on a condition of successful reception of the DCI message, selecting, by the WTRU, one or more GL-PUSCH frequency resources from the subset of the set of GL-PUSCH frequency resources and a time period; transmitting, by the WTRU, data on a GL-PUSCH using the selected one or more GL-PUSCH frequency resources during the selected time period; determining, by the WTRU, a time location for reception of hybrid automatic repeat request acknowledgement (HARQ-ACK), associated with the transmitted GL-PUSCH data, based on the selected one or more GL-PUSCH frequency resources; and monitoring, by the WTRU, for reception of the HARQ-ACK during the determined time location.
2. (canceled)
3. The method of claim 1, wherein the DCI message is a common DCI message.
4. The method of claim 1, wherein the selection of the one or more GL-PUSCH frequency resources from the subset of GL-PUSCH frequency resources is determined randomly.
5. The method of claim 1, wherein the selection of the one or more GL-PUSCH frequency resources from the subset of GL-PUSCH frequency resources is determined based on a WTRU-ID.
6. The method of claim 1, wherein the selection of the time period is determined randomly.
7. The method of claim 1, wherein the selection of the time period is determined based on a WTRU-ID.
8. The method of claim 1, wherein the monitoring for the DCI message occurs during a first fixed time window.
9. The method of claim 1, wherein the time period is within a second fixed time window.
10. The method of claim 1, wherein the determination of the time location is further based on a GL-PUSCH resource index.
11. A method for use in a wireless transmit/receive unit (WTRU) for wireless communications, the method comprising:
determining, by the WTRU, a time location for reception of hybrid automatic repeat request acknowledgement (HARQ-ACK), associated with transmitted GL-PUSCH data, based on one or more GL-PUSCH frequency resources used to transmit the GL-PUSCH; and monitoring, by the WTRU, for the reception of the HARQ-ACK during the determined time location.
12. The method of claim 11, wherein the determination of the time location is further based on a GL-PUSCH resource index.
13. A wireless transmit/receive unit (WTRU) for multiple access wireless communications, the WTRU comprising:
a transceiver configured to receive a configuration of a set of grant-less Physical Uplink Shared Channel (GL-PUSCH) frequency resources; the transceiver operatively coupled to a processor, the transceiver and the processor configured to monitor for a downlink control information (DCI) message, wherein the DCI message includes an indication of a presence of at least a subset of the set of GL-PUSCH frequency resources; the processor configured, on a condition of successful reception of the DCI message, to select one or more GL-PUSCH frequency resources from the subset of the set of GL-PUSCH frequency resources and a time period; the transceiver configured to transmit data on a GL-PUSCH using the selected one or more GL-PUSCH frequency resources during the selected time period; the processor configured to determine a time location for reception of hybrid automatic repeat request acknowledgement (HARQ-ACK), associated with the transmitted GL-PUSCH data, based on the selected one or more GL-PUSCH frequency resources; and the transceiver and the processor configured to monitor for reception of the HARQ-ACK during the determined time location.
14. (canceled)
15. The WTRU of claim 13, wherein the DCI message is a common DCI message.
16. The WTRU of claim 13, wherein the selection of the one or more GL-PUSCH frequency resources from the subset of GL-PUSCH frequency resources is determined randomly.
17. The WTRU of claim 13, wherein the selection of the one or more GL-PUSCH frequency resources from the subset of GL-PUSCH frequency resources is determined based on a WTRU-ID.
18. The WTRU of claim 13, wherein the selection of the time period is determined randomly.
19. The WTRU of claim 13, wherein the selection of the time period is determined based on a WTRU-ID.
20. The WTRU of claim 13, wherein the monitoring for the DCI message occurs during a first fixed time window.
21. The WTRU of claim 13, wherein the time period is within a second fixed time window.
22. The WTRU of claim 13, wherein the determination of the time location is further based on a GL-PUSCH resource index.
